Professional wrestling utilizes the structure of title matchcombat sports. Participants compete for a championship, and must defend it after winning it. These titles are represented physically by a championship belt that can be worn by the champion. In the case of team wrestling, there is a belt for each member of the team.

Almost all professional wrestling promotions have one major title, and some have more. Championships are designated by divisions of weight, height, gender, wrestling style, and other qualifications.

Typically, each promotion only recognizes the "legitimacy" of their own titles, although cross-promotion does happen. When one promotion absorbs or purchases another, the titles from the defunct promotion may continue to be defended in the new promotion or be decommissioned, usually through championship unification.

Behind the scenes, the bookers in a company will place the title on the most accomplished performer, or those the bookers believe will generate fan interest in terms of event attendance and television viewership. Lower ranked titles may also be used on the performers who show potential, thus allowing them greater exposure to the audience. However, other circumstances may also determine the use of a championship. A combination of a championship's lineage, the caliber of performers as champion, and the frequency and manner of title changes, dictates the audience's perception of the title's quality, significance, and reputation.

A wrestler's championship accomplishments can be central to their career, becoming a measure of their performance ability and drawing power. The most accomplished or decorated wrestlers tend to be revered as legends. American wrestler Ric Flair has had multiple world heavyweight championship reigns spanning over three decades. Japanese wrestler Último Dragón once held and defended a record 10 titles simultaneously.

Professional wrestling's championship belts are modeled similarly to the championship belts in boxing, and other combat sports such as mixed martial arts. They are made of elaborately designed plates of gold or other precious metals, usually bearing the name of the title and the wrestling promotion, and is on a leather strap. The color and designs vary with each title and promotion.

A wrestler may win a sanctioned championship and redesign the belt itself. Some such as John Cena's Spinner Belt) later became the official belt design. Others (such as Stone Cold Steve Austin's Smoking Skull Belt and Edge's Rated-R Spinner) were not used after their respective title reign.

While rare, there are cases of championships being represented with items other than belts, such as championship trophies, medals, crowns etc.

The fate of a title depends on the champion's condition and the importance of the title to the promotion (e.g. Gregory Helms held the WWE Cruiserweight Championship, despite being sidelined with an injury, because the Cruiserweight Championship was not a major championship). The champion may be forced to vacate his or her title if the injury becomes too severe and the championship is too important. In May 2015, Daniel Bryan vacated the WWE Intercontinental Championship due to a major concussion and a year before, he had to vacate the world title due to neck surgery. Later that year, Seth Rollins vacated the WWE Championship due to a knee injury.

Before the 1980s when title matches were rare some champions could keep their titles even when injured; Bruno Sammartino kept his WWWF World Heavyweight Championship from April to June 1976 despite being injured by a botched body slam from Stan Hansen. In Mexico this situation still occurs, but in Japan it is becoming increasingly rare as champions are needed to be present in regular tours even when titles are not defended.

The world heavyweight championship (also just world championship) is the name given to the championship that is presented as being the most prestigious of those contested within a promotion. The wrestler holding a championship with this name is most commonly referred to as the "world heavyweight champion" (though some promotions may use synonymous/alternate terms, such as the AAA Mega Championship of AAA or the WWE Universal Championship, one of two world titles of WWE, for examples).

The first recognized world heavyweight championship was the World Heavyweight Wrestling Championship, created in 1905, and the inaugural champion was George Hackenschmidt. The lineage of many prominent contemporary world championships can be traced back to the World Heavyweight Wrestling Championship.

Another common classification of championships are by weight classes. Given the scripted nature of professional wrestling matches, weight classes aren't always strictly adhered to. Typically, promotions prefer to have a heavyweight title as their top prize, with other designators such as cruiserweight, middleweight, or light-heavyweight titles. Promotions often have one sub-heavyweight classification, while others sometimes may have more. Mountevans' committee (a governing body that instilled rules for professional wrestling in the UK) created seven formal weight divisions:

Lightweight (154 pounds (70 kg))

Welterweight (165 pounds (75 kg))

Middleweight (176 pounds (80 kg))

Heavy middleweight (187 pounds (85 kg))

Light heavyweight (198 pounds (90 kg))

Mid-heavyweight (209 pounds (95 kg))

Heavyweight (above 220 pounds (100 kg))

Classifying championships into weight classes is also common practice in the lucha libre promotions of Mexico. Lucha libre has a detailed weight class system patterned after boxing. Each weight class has an official upper limit, but examples of wrestlers who are technically too heavy to hold their title can be found. The following weight classes exist in lucha libre, as defined by the "Comisión de Box y Lucha Libre Mexico D.F." (the Mexico City Boxing and Wrestling Commission), the main regulatory body in Mexico:[1]

Gender occasionally plays a role in the classifications of championship belts. For gender-specific titles, the classification "Women's" is often included at the beginning of the championship's name. Due to professional wrestling generally being a sport dominated by men, only women's titles are given official gender classifications. Generally, only men are allowed to win the championships without a gender specification, though Chyna winning the WWF Intercontinental Championship in 1999 from Jeff Jarrett is a notable exception. In promotions featuring only a single gender (such as Women of Wrestling or Shimmer Women Athletes), gender classifications are often unnecessary as well.

Andy Kaufman once used gender classifications to his advantage, turning inter-gender competitions into a unique wrestling side-show. Kaufman declared himself the "Inter-Gender Champion of the World", and offered $1,000 to any woman who could pin him. None were successful during the run of the gimmick; though in other promotions such as WCW and WWE, women have successfully pinned men, most notably in a few isolated championship matches.

Gimmick match classifications sometime come into prominence in the creation of title belts. In these classifications, special skill in a certain type of match or a certain style of wrestling is the signature of the division, and the champion is considered to be the most skilled wrestler at that specific style.

Gimmick championships often take very differing forms. A common variation is the "hardcore championship", which are defended in a rules light, and often weapons-filled and bloody competition. An example of a hardcore championship is the WWE Hardcore Championship, which was active from 1998 to 2002.

Another common variation is a "television championship", which involves more frequent title defenses as well as the stipulations that the belt can only change hands on television (as opposed to non-televised house shows) with title matches having a short, TV-friendly time limit, usually 10 of 15 minutes. These titles were originally introduced during a time when weekly TV shows were seen as a vehicle to promote the money-making live shows, where major title defenses took place. Television titles provided a championship that would be defended on the weekly television shows. Examples of a television championship include the WCW World Television Championship, the ECW World Television Championship, and the ROH World Television Championship.

Tag team championships are yet another different form of wrestling title. Some consider it to be a style championship, but tag team championships are unique in their ability to include multiple wrestlers on teams competing for multiple belts. The most common form of tag team championships are in 2-on-2 format, which is often implicitly understood. Other tag team championships include 3-on-3 and 4-on-4 formats, which are often explicitly stated within the championship name to distinguish them from the 2-on-2 championships.

The concept of championships, and their central role in wrestling, allow for the potential for angles. One such angle is an unsanctioned championship title. These are claimed by a wrestler and defended in sanctioned matches, but are not recognized as legitimate titles by the promotion.
